  • Patent number: 9411338
    Abstract: A cleaning robot (1) which is an autonomous mobile system performs coordinate conversion of three-dimensional coordinate data acquired by measurement in a distance image sensor (20) which is arranged in a frontward and obliquely downward direction to generate three-dimensional coordinate data of a floor surface reference. Labels are applied to this data by judging a level difference or an obstacle according to height from a floor surface (F) to create overhead view image data seen from directly above a cleaning robot main body. The overhead view image data is scanned, and only when the labels are arranged in a specific order, processing for substituting an unspecified area with a level difference is performed. Thereby, positional deviation of an edge of the level difference, which is caused by a blind spot, is corrected and a position of the level difference is able to be grasped accurately.

  • Publication number: 20080298817
    Abstract: A light receiving device includes a frame 1, and a light-receiving element 2 placed on one surface side of the frame 1. The other surface of the light-receiving element 2 opposite to the frame 1 side, as well as the frame 1, are grounded. Thus, the GND potential is present on the one surface side of the light-receiving element 2, while the other surface of the light-receiving element 2 is also of the GND potential. Consequently, there is provided a light receiving device being small-sized and having an effective noise shielding effect as well as high heat radiation property.

  • Patent number: 7171127
    Abstract: An optical transmission controller includes a semiconductor-laser, a semiconductor laser driver, a monitor photoreceptor, a waveform detector and a phase relation adjuster. The semiconductor laser driver allows the semiconductor laser to output an optical signal. The monitor photoreceptor monitors the optical signal output. The waveform detector detects a fall state of the optical signal output. The phase relation adjuster adjusts a phase relation between a fall timing of an input current and a variation timing of a relaxation oscillation of the optical signal output in accordance with a detection result of the waveform detector.

  • Patent number: 6845182
    Abstract: A CPU detects the available space A of a first recording medium, the available space B of a second recording medium and a preprogrammed image information amount C necessary for preprogrammed recording by first and second recording medium space managing portions and the contents of preprogrammed recording input from an operation portion by the user. When the preprogrammed image information amount C is larger than the available space A of the first recording medium, an amount of shortage in recording space for preprogrammed information D is obtained from the CPU by subtracting the available space A of the first recording medium from the preprogrammed image information amount C. A larger amount of image information than the recording space shortage D is selected from the image information stored on the first recording medium, and the selected image information is moved to the second recording medium.
